Tire tread



FIG. 1 is a perspective view of a tire tread, showing my new design, it being understood that the pattern shown repeats uniformly throughout the circumference of the tread;

FIG. 2 is a front elevational view thereof;

FIG. 3 is a right side elevational view thereof, the opposing side being a mirror image thereof; and,

FIG. 4 is an enlarged fragmentary front view thereof showing the tread pattern in greater detail.

The broken line showing of a tire sidewall and inner bead, including the peripheral boundary between the claimed tread portion and the sidewall, represents unclaimed environmental subject matter. 

The ornamental design for a “tire tread,” as shown and described.
